SHIELDED SYSTEM OF WIRELESS MULTI-POSITION CHARGING OF MOBILE DEVICES Russian patent published in 2014 - IPC H02J7/00 

FIELD: electricity.

SUBSTANCE: wireless multi-position charging system comprising a base unit in the form of one or several surfaces equipped with power transmitters, developing alternating magnetic field due to supply of AC current to a winding, coil or any type of current-conducting wires, grouped into a lattice, and also from a device of energy reception comprising a circuit of power supply control and a receiving coil, which induces current in the magnetic field of the transmitting coil, differing by the fact that it additionally includes: a shielding structure made as capable of weakening intensity of electromagnetic field outside the shielded wireless multi-position charging device; passive retransmitting antennas built into the charging device; a device of charging device adaptation to arbitrary arrangement of charged devices on the surface of the charging device.

EFFECT: reduced incidental electromagnetic emission.
